我正在绘制一个双变量密度图，每个变量都有边际图。我发现结果过于平滑，因此我尝试减少带宽。但是，当我尝试使用bw参数时，它只会更改x边际图。
是否有一种简单的方法来更改x和y边际图的带宽？
g=sns.jointplot(x=xvar, y=yvar, kind='kde',marginal_kws=dict(bw=0.8),bw=0.8)

最佳答案
如果需要更多控制，则必须直接使用JointGrid：
iris = sns.load_dataset("iris")
g = sns.JointGrid(x="sepal_width", y="petal_length", data=iris, space=0)
g = g.plot_joint(sns.kdeplot, cmap="Blues_d")
sns.kdeplot(iris["sepal_width"], color="b", shade=True, bw=0.1, ax=g.ax_marg_x)
sns.kdeplot(iris["petal_length"], color="r", shade=True, bw=0.01, vertical=True, ax=g.ax_marg_y)
